psp go wont go into recovery mode

my psp go running 6.39pro b9
cant seem to get it into recovery mode
ok from xmb click on the fast recovery mode which works
checked in the system setting its running on the PRO NIGHTLY
when i hold the power button for 4 sec and release it while holding the rt bumper button
sony logo appears and it restarts but when i check it its in the ofw 6.39 fw
what am i doing wrong here
any comments

you have lcfw which means at a shutdown you must restart the cfw and enable in the xmb again so this is not the way you can go to the recovery mode as on shutdown the cfw is wiped from the ram of the psp so what you have to do is enable pro again by using fastrecovery and then open vsh menu by pressing select and from there go to the option access recovery mode and press x walllah ur in recovery mode

is there any new version of 6.39 pro b9 which is not just pro b9
as you have said in another post it gets updated daily the NIGHTLY one
where can i download it
is my current cfw outdated or right one for me to use
what do you recommend

well i would say the most stable is 6.39 pro b8 because b9 are betas and the nightly builds are open source made from people so they are not advised unless you go for some experimenting though i would say ur cfw is just fine for ur use

put back the folders of 6.39pro b-9 oprn the updater and there would be an option of uninstalling the firmware press the button and when ur done remove the folders and download pro b-8 place its folders except for cipl flasher which u dont need and install it report here if it worked
